7.6) Troubleshooting guide

Table 23 provides some useful information to deal with any malfunc-
tions that may occur during installation, or in the event of faults.
Table 23: troubleshooting
SYMPTOM
The radio transmitter does not control the door
and the transmitter led does not illuminate
The radio transmitter does not control the door
but transmitter led illuminates
...no manoeuvre is activated and the OK led
does not flash
...no manoeuvre is activated and the flashing
light is off
...the manoeuvre does not start and the flashing
light flashes a few times
The manoeuvre starts but immediately afterwards
a brief inversion is activated.
7.7) Diagnostics and indicators
Some devices offer special direct indicators to display the relative operating status or malfunctions.
7.7.1) Signals with flashing light
If a flashing light is connected it emits one flash per second during the manoeuvre; in the event of faults, the flashing frequency increases
with flashes repeated twice, separated by a pause of a second (Table 23). The same conditions apply to the courtesy light.

PROBABLE CAUSE AND POSSIBLE REMEDY
Check that the transmitter batteries are not discharged; replace if necessary.
Check that the transmitter is correctly memorised on the radio receiver.
Ensure correct emission of the radio signal of the transmitter with the following empirical
test: Press a key and place the led against the aerial of a standard radio (the cheaper the
better) switched on and tuned to FM at the frequency of 108.5Mhz or as close to this
value as possible; a slight noise with a scratching pulse noise should be heard.
Ensure that TEN is powered from a 230V mains. Check that fuses F1 and F2 are not
blown; in this case, identify the cause of the fault and then replace with versions of the
same current value and specifications (Figure 40).
Check that the command is effectively received. If the command reaches the SS input
and the led OK emits a double flash to indicate that the command has been received.
Count the number of flashes and check with reference to the data in Table 24.
The selected force may be too low to move the door. Check whether there are any
obstacles, and if necessary select a higher force.
Cause

Activation of Motor Force

ACTION
At the start of the manoeuvre one or more photocells do not enable the move-
ment; check for the presence of obstacles
During closure this is normal if an obstacle is effectively present
During movement, the door is subject to points of increased friction; check cause.
At the start of or during movement, the STOP input is activated; check cause
Wait at least 30 seconds and retry a command; if the condition persists, this may
indicate a serious fault and the electronic board needs to be replaced
Wait a few minutes for the manoeuvre limiter to return within the maximum limit
Disconnect all power circuits for a few seconds and then retry a command; if the
condition persists this may indicate a serious fault with the board or motor wiring.
Check and make replacements as necessary.
